Find Blue Lacy Puppies For Sale on Pets4You.com. The Lacy Dog or Blue Lacy Dog is a breed of working dog that originated in Texas in the mid-19th century. The Lacy was first recognized in 2001 by the Texas Senate. In Senate Resolution No. 436, the 77th Legislature honored the Lacy as "a true Texas breed". In June 2005, Governor Rick Perry signed the legislation adopting the Blue Lacy as "the official State Dog Breed of Texas". As expected, the vast majority of Lacy dogs are found in Texas. However, as the breed becomes more well recognized, there are breeding populations being established across the United States, Canada, and most recently in Europe.
